Very few things will be as widely useful as OOP or namespaces, so that
comparison is a bit of a red herring.  This construct is useful
anywhere function call nesting pushes you past a readability
threshold.  That's not as ubiquitous as OOP as a whole, but it's
pretty widespread.  As widespread as fluent call chaining, in fact.

Agreed.  There's a cost to every new token and parser rule on the
compiler side, and there's a cognitive overhead on the script
maintainer side as well.  It seems we only disagree in the flexibility
provided by better syntax and the ease of using google,
stack-overflow, and php.net/manual.

And I'll expect you to vote accordingly. No hard feelings. :)
